<p>Test::Harness::Straps - detailed analysis of test results</p>

<h1 id="SYNOPSIS">SYNOPSIS</h1>

<pre><code>  use Test::Harness::Straps;

  my $strap = Test::Harness::Straps-&gt;new;

  # Various ways to interpret a test
  my $results = $strap-&gt;analyze($name, \@test_output);
  my $results = $strap-&gt;analyze_fh($name, $test_filehandle);
  my $results = $strap-&gt;analyze_file($test_file);

  # UNIMPLEMENTED
  my %total = $strap-&gt;total_results;

  # Altering the behavior of the strap  UNIMPLEMENTED
  my $verbose_output = $strap-&gt;dump_verbose();
  $strap-&gt;dump_verbose_fh($output_filehandle);</code></pre>

<h1 id="WARNING">WARNING</h1>

<p><b>THIS MODULE IS FOR BACKWARDS COMPATIBILITY ONLY!</b> No further development is planned, no bugs will be fixed.</p>

<p>For customizable TAP parsing please use <a href="https://metacpan.org/pod/TAP::Parser">TAP::Parser</a> instead.</p>

<h1 id="DESCRIPTION">DESCRIPTION</h1>

<p>Test::Harness is limited to printing out its results. This makes analysis of the test results difficult for anything but a human. To make it easier for programs to work with test results, we provide Test::Harness::Straps. Instead of printing the results, straps provide them as raw data. You can also configure how the tests are to be run.</p>

<p>The interface is currently incomplete. <i>Please</i> contact the author if you&#39;d like a feature added or something change or just have comments.</p>

<h1 id="CONSTRUCTION">CONSTRUCTION</h1>

<h2 id="new()"><a id="new"></a>new()</h2>

<pre><code>  my $strap = Test::Harness::Straps-&gt;new;</code></pre>

<p>Initialize a new strap.</p>

<pre><code>  $strap-&gt;_init;</code></pre>

<p>Initialize the internal state of a strap to make it ready for parsing.</p>

<h1 id="ANALYSIS">ANALYSIS</h1>

<h2 id="$strap-&gt;analyze(-$name,-\@output_lines-)"><a id="strap--analyze---name---output_lines"></a>$strap-&gt;analyze( $name, \@output_lines )</h2>

<pre><code>    my $results = $strap-&gt;analyze($name, \@test_output);</code></pre>

<p>Analyzes the output of a single test, assigning it the given <code>$name</code> for use in the total report. Returns the <code>$results</code> of the test. See <a href="https://metacpan.org/pod/Results">Results</a>.</p>

<p><code>@test_output</code> should be the raw output from the test, including newlines.</p>

<pre><code>    my $results = $strap-&gt;analyze_fh($name, $test_filehandle);</code></pre>

<p>Like <code>analyze</code>, but it reads from the given filehandle.</p>

<h2 id="$strap-&gt;analyze_file(-$test_file-)"><a id="strap--analyze_file---test_file"></a>$strap-&gt;analyze_file( $test_file )</h2>

<pre><code>    my $results = $strap-&gt;analyze_file($test_file);</code></pre>

<p>Like <code>analyze</code>, but it runs the given <code>$test_file</code> and parses its results. It will also use that name for the total report.</p>

<p>Returns the full command line that will be run to test <i>$file</i>.</p>

<p>Returns the command that runs the test. Combine this with <code>_switches()</code> to build a command line.</p>

<p>Typically this is <code>$^X</code>, but you can set <code>$ENV{HARNESS_PERL}</code> to use a different Perl than what you&#39;re running the harness under. This might be to run a threaded Perl, for example.</p>

<p>You can also overload this method if you&#39;ve built your own strap subclass, such as a PHP interpreter for a PHP-based strap.</p>

<p>Formats and returns the switches necessary to run the test.</p>

<p>Returns only defined, non-blank, trimmed switches from the parms passed.</p>

<pre><code>  local $ENV{PERL5LIB} = $self-&gt;_INC2PERL5LIB;</code></pre>

<p>Takes the current value of <code>@INC</code> and turns it into something suitable for putting onto <code>PERL5LIB</code>.</p>

<pre><code>  my @filtered_inc = $self-&gt;_filtered_INC;</code></pre>

<p>Shortens <code>@INC</code> by removing redundant and unnecessary entries. Necessary for OSes with limited command line lengths, like VMS.</p>

<pre><code>  $self-&gt;_restore_PERL5LIB;</code></pre>

<p>This restores the original value of the <code>PERL5LIB</code> environment variable. Necessary on VMS, otherwise a no-op.</p>

<h1 id="Parsing">Parsing</h1>

<p>Methods for identifying what sort of line you&#39;re looking at.</p>

<pre><code>    my $is_diagnostic = $strap-&gt;_is_diagnostic($line, \$comment);</code></pre>

<p>Checks if the given line is a comment. If so, it will place it into <code>$comment</code> (sans #).</p>

<pre><code>  my $is_header = $strap-&gt;_is_header($line);</code></pre>

<p>Checks if the given line is a header (1..M) line. If so, it places how many tests there will be in <code>$strap-&gt;{max}</code>, a list of which tests are todo in <code>$strap-&gt;{todo}</code> and if the whole test was skipped <code>$strap-&gt;{skip_all}</code> contains the reason.</p>

<pre><code>  my $is_bail_out = $strap-&gt;_is_bail_out($line, \$reason);</code></pre>

<p>Checks if the line is a &quot;Bail out!&quot;. Places the reason for bailing (if any) in $reason.</p>

<pre><code>  $strap-&gt;_reset_file_state;</code></pre>

<p>Resets things like <code>$strap-&gt;{max}</code> , <code>$strap-&gt;{skip_all}</code>, etc. so it&#39;s ready to parse the next file.</p>
